METAL-ROLLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 250,678, dated December13, 1881.

Application filed March 24, 1881.

To all whom it may concern:

Be it known that I, SAMUEL F. REYNOLDS, of Auburn, in the county ofCayuga and State of New York, have invented certain new and usefulImprovements in Metal Rolling Machines; and I do hereby declare thatthe'followingis at'ull, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference beinghad to the accompanying drawings,and to theletters of reference marked thereon, which form a part of thisspecification.

My invention relates to metal-rolling machines; and it consists in theconstruction and arrangement of parts, as hereinafter more fullydescribed and claimed.

In the annexed drawings, in which like parts are indicated by likeletters inthe several views, Figure 1 is a plan view of the machine.Fig. 2 is an end view. Fig. 3 is a vertical section on the line 00 m,and Figs. 4 and 5 are detail views of dies.

A represents the frame of the machine, which is constructed of suitablematerial and arranged with braces A A and cross-rods a a, to strengthenand support the operative parts. At one end of the frame A is journaleda driving-shaft, B, that carries at either end the cogged gears orpinions b b. The pinion 1) gears with a cogged wheel, B, which, in turn,engages above with a cogged wheel, 0.

0n the shaft B, that carries the gear-wheel B, is a pinion, I), thatengages above with the cogged periphery of a recessed disk, D, on theshaft (1. The adjoining disk D, revolving in the opposite direction onits shaft cl, is driven by the pinion c on the shaft 0, that is operatedby the gear-wheel O. The opposite sides of the frame A are connected andstrengthened by the cross rods or braces a a, which are screw-threadedat their ends and provided with nuts a a, by which they may betightened, so as to steady the machine.

E E are the bearings or journalboxes for the operating-shafts.

In machines for rolling wagon-axles I have found it convenient anduseful, especially in forming that part of the axle on which the wheelrevolves with a shoulder or collar, to provide the machine with tworevolving disks carryin g dies, and arranged to be operated by cog-(ModeL) gearings, so as to revolve in opposite directions with equalspeed. The dies that are arranged within the recessed disks are soconstructed as to cause the iron of which the axle is formed to rollbetween them sidewise.

The recessed disks D D are provided on one side with ribs 0 e, thatradiate from the center and assist in supporting the dies F, which areeach provided with a V-shaped notch for the reception of theribs. Thedie F is provided with a groove, f,for forming the collar or shoulder,and with a depression, f, for breaking the iron down gradually. It is ofgreater thickness at the center than on the outer side, and that portionof the die that forms the collar gradually increases in thickness fromthe point 9 to h, the outer side of the die remaining the same fromthelatter point to t, whence it gradually decreases to the pointj; butthe inside of the die is thicker at k than at I, thus making theirontnperin g as it passes between the points is and l. The die F (shown inFig. 5) is a development of the circular die F, and is intended for usein machines provided with sliding plates or beds.

Attached to the cross-pieces A A, and arranged between the revolvingdisks D D, are beveled guides G G, that hold the iron in position andprevent it from slipping on the. dies. The manner in which these guidesare arranged enables the machine to be operated from either Side, thecrosspieces A A being perforated at a for the passage of the metal bar.

From the foregoing description the operation and advantages of mymachine will be apparent.

When constructing wagon or car axles, carpins, studs for looms, andsimilar pieces of metal-work requiring a shoulder, the meta bar ispassed through the opening a from either end of the machine. The metalis held by the guides Gr G to the action of the dies, which arerevolving in opposite directions with equal speed. In this operation thedepressed portions of the dies break the iron down gradually, while thegroove forms the collar or shoulder, and the thick central parts of thedies finally smooth and finish the work from the shoulder to the end ofthe bar. I find by experience that when an attempt is made to form theshoulder and break down the whole arm at once the outer side of themetal will draw faster than the center of the bar, thus forming acoldshut or leaving the end of the axlearm hollow; but when the faces ofthe dies are made with a gradual increase, so as to break the iron downuntil it is of sufficient length before the thick central portions ofthe dies pass over it, the work, when finished, will be left solid atthe ends. By the time the collar is formed the disks carrying the dieswill reach a point during their revolution in opposite directions inwhich the V-shaped notches in the dies will coincide with the spacesbetween the guides, so that the finished axle or other article may bereadily removed.

Having thus described my invention,what1 claim asnew, and desire tosecure by Letters Patent, is

1. In a metal-rolling machine, the diesF,hav-

ing inclined edges, and provided with groovef 20 and depression f,substantially as specified.

2. In a metal-rollin g machine, the dies F F, having on one side aV-shaped notch, and provided with groove f and depression f, incombination with the recessed and toothed disks 25 D D having ribs 0 e,substantially as set forth.

3. In a metal-rolling machine, the'combination of the dies F F, havinggroovesf and depressions f, recessed disksD D, provided with ribs 0 e,and the beveled guides Gr G, substano tially as shown and described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
